I set up corebos using the smtp-relay.gmail.com configuration and it says it is sending the test email if I use the YES option for authentication (But I have yet to receive a test email or see one come across gmails spam blocker or inbox. (I can see reports from my admin console))

Am I missing something?

Are there settings I am not seeing?

Thanks all for your help

P.s. I also added the IP address I think my corbos server has to the SMTP whitelist in my Gsuite account.
p.p.s It also says it sends with TLS Certificate Validations but none of the other options
